piston ring: [noun] a springy split metal ring for sealing the gap between a piston and the cylinder wall.

Headland Rings. A Headland piston ring is a metal ring that is placed around the top of the piston in a diesel engine. It is shaped like a half-dome and it has a flat top with two parallel sides. The sides of the ring flare outward at the top and meet at a peak which is where the head of the ring is located.

For high performance engines, the multiplier changes to add more clearance, but the math stays the same: Modified or Nitrous Oxide - 0.005in x 4.00in bore = 0.020 inch ring gap. High Performance Racing - .0055in x 4.00in bore = 0.022 inch ring gap. Racing with Nitrous/Turbo - 0.006in x 4.00in bore = 0.024 inch ring gap.

What causes piston rings to stick? Gasoline byproducts can form deposits, too. Heavy deposits cause the rings to stick in the grooves rather than stand proud of the piston, allowing a gap to form between the ring and cylinder wall, which invites blow-by and oil consumption.

Simply put, piston rings form a seal between the piston and cylinder wall, which prevents pressurized combustion gases from entering the oil
